THOMAS, OFLYNN'EIELD, MASSACHUSETTS, ASSIGNOR 'lO UNITE-D SHOE G15 TEJEERSQN, NEWJERSEY, A GORPOB'ATIO'N OF NEW SHOE resume Meormm Application-filed June29, 1329. Serial No. 374,762 r This invention relates to shoe turningmachines and is herein illustrated, as embodied in a shoe turningmachine in which the forepart of a shoe is turned by power-operatedinstrumentaliti s; v M

Turn shoes are sewed'wrong side out and after the sewing has beencompleted they are commonly turned right side out by machines of thetype disclosed in the application for United States Letters Patent ofEdward Erickson, Serial No. 733,112, filed August 20, 1924. In machinesof the type disclosed in the abovementioned application vco-operatingheel turning members are first operated to turn the heel part of a shoeand are thereafter locked in position to clampthe heel seat of the shoeand thereby hold the shoe firmly during the subsequent turning ofitheforepart. I

The forepart'turning instrumentalitijes of machines of theabove-mentioned type 00111- prise a sole support over whichthe sole ofthe shoe is bent by the operator after the heel seat has been clamped, aturning iron arranged to engage the toe of the upper, and a forepartspreader which is normally maintained in an out-of-the-way position andis manually inserted in the forepart of the shoe before theforepartturning operation is commenced. The turning iron of such amachine is first moved into engagement with the toe of the shoe andthereafter all three members are moved simultaneously in the samedirection to eliect the turning ofthe forepart of the shoe. the turningiron moving at twice the speed of the sole support and the forepartspreader being merely pushed out of the way by the turning iron, As aresult the forepa-rt of the shoe is gradually stripped of? from theforepart spreader and turned rightsidc out upon the turning iron.Continued operation of the machine under power serves to retract theturning iron and the sole support to their initial positions, to unlockthe heel turning; members from their clamping positions, and toreleasethe forer-art spreader to enable it tobe returned to its normal.out-o't-the-way position, thereby completing a cycle of operations.

In certain styles of shoes, such as variou strap shoes and pumps whichhave recently been made in considerable quantities, the throatopeningthroughwhich the sole has to be passed to accomplishthe turningof the iorepart of the shoe is liable to be smaller than vin shoes ascommonly designed heretofore and, because of the improved design andtighter lasting of the upper materialsthis throat opening is usuallyless readily adaptable to accommodate the passage therethrough of thewidest portion of the sole, In

these recently designed shoes, accordingly, it is often unusuallydifiicult to turn the foreparts without tearing or otherwise injuringthe uppers.

One object of the present invention is to provide an improved shoeturning machine or" the type referred to which will be as satisfactoryin operation for turning shoes of the types heretofore made as themachines formerly employed but which will be even better adapted forturning the newer types of shoes with the smaller throat openings abovementioned. v With this object in view, one feature of the presentinvention consists in the provision, in a shoeturning machine, of twomembers constructed and arranged to co-opcrate in turning a shoe, andoperating mechanism for said members constructed and arranged to impartan operativemovement to one of the members and, simultaneously with theinitiation of said operative movement, tomove the other turning memberat a dlfferent speed from that of the first member to cause it toco-operate with the first member, such an organization insuring improvedco-operation of the shoe turning members for the purpose'of insuringthat the shoe uppers will not be subjected to excessive strain oring'the turning operation and particularly to facilitate the passage of thewidest portion of a sole through the narrow throat opening of the upper.In the illustrated machine improved co-operation of two forepart turningmembers consisting of a turning iron and a sole support is insured bythe combination with a carrier upon which said members are movablymounted, of a rack bar movable relatively to the carrier,- clutchmechanism for connecting the sole support, the carrier and the rack barfor movement in unison, and gearing incontinuous driving engagementwiththe rack bar and with the turning iron and operable simultaneously withthe initiation of the movement of the sole sup: port to move the turningiron at twice the speed of the sole support to co-operate with betweenthe turning instrumentalities and the source of power, and the membersof which are adjustable to adapt them to slip under different loadconditions.

In accordance with another feature of the invention, as hereinillustrated, the means controlled by the actuation of the forepartturning means for locking the heel'turning members to clamp the heelseat of the shoe includes a roll clutch, a clutch of this type havingbeen found most reliable for this particular purpose because it exertsits full clutching engagement without any yielding movement on the partof the members which it engages, and thereby eliminates any tendency onthe part of the turning members to ease up in their clamping pressureupon the heel seat.

In accordance with a furtherfeature of the invention an improvedmechanism for controlling the stopping and starting of the machine isprovided; This control-mechanism has a manually operable member wherebythe operator can aetuate'the mechanism to start the machine, themechanism itself being constructed and arranged to stop the machineautomatically upon the completion of a cycle, even if the operatorinadvertently should retain his grasp upon the control member and holdthis member in starting position. In addition to the above-mentionedmechanism, and associated'therewith, the illustrated machine is providedwith operatorcontrolled means for disengaging the driving means fromtheshoe turning means, an advantage of this additional feature beingthat it enables the operator to stop the machine at any point in thecycle of operations when he thinks it necessary to avoid injury to ashoe.

Other features of the inventionconsist in the provision of improvedadjustments for the forepart spreader and forthe heel turninginstrumentalities and in certain novel features of construction andcombinations and arrangements of parts hereinafter described andclaimed, the advantages of which will be obvious to those skilled in theart.

The illustrated machine is provided with instrumentalities which operatefirst to turn the heel port-ion of ashoe and then to hold the heelportion clamped while other instrumentalities of the machine operate toturn the forepart. The various turning instrumentalties are carried upona head 20 (Fig. 1)

which is mounted upon a standard 22.

For turning'the heel portion of the shoe a plurality of stationarymembers 24: (Figs.

1, 4. 12 and 13) which are designed for operation upon various types ofshoes respectively are carried by a turret 26 which is mounted forrotation in a horizontal plane upon the head 20. In order to hold theturret 26 in position to maintain any one of the stationary heel turningmembers 24 in operating position, a spring latch 28 is mounted upon thehead 20 so as to engage one of a plurality of recesses 30 formed in theturret 26. The

shanks of the stationary turning members 24: are received insockets 32which are clamped in an arcuate slot 34 formed in the turret 26 and aresecured in this slot by means of bers 24 With respectto the turret 26and about shanks are inserted in the sockets to provide for longitudinaladjustment of these members, that is, adjustment of the radial distancesbetween the axis of the turret 26 and each of the stationaryheel turningmembers 24. Cooperating with the stationary heel turning members 24 area plurality of heel 1 cups 42 which are designed for operation uponvarious types of shoes respectively, and which are carried upon a turret44 mounted on a lever 46 which is fulcrumed at 48 upon the head 20. Thelever 46 may be swung about its fulcrum to bring one of the' heel cups42 into engagement with one of the stationary heel turning members 24 bymeans of a rod 50 connected to a treadle lever 52 having a hingedextension 54 which" carries a treadle. A spring 56 normally holds thetreadle lever 52 up and the cup members 42 down and away from thestationary heel turning members 24. A spring 58 surrounding the rod 50and interposed between an abutment on the head 20 and a nut on the rod50 serves to cushion the downward movement of the various memberscarried by the lever 46 when the treadle 54 is released by the operator.The heel cups 42 are adjustably carried upon the turret 44 by means ofbolts 60 which extend through slots formed in the turret 44. The turret44 may be rotated about its axis to bring any one of the several heelcups 42 into operative relation with respect to the desired stationarymember 24 which has already been secured in operativg position. A springlatch 62 '(Fig. 13) serves to hold the turret 44 in one of a pluralityof positions to maintain a selected heel cup in operative relation to aselected stationary heel turning member. A clamping bolt 64 is employedto exert pressure through a cap 66 and thereby clamp the hub of theturret 44 as a further security against undesired movement. The turningof the heel portion of a shoe S (Figs. 12 and 13 is accomplished bybringing a selectively positioned heel cup 42 with the shoe supportedthereon towarda selectively positioned stationary member 24, causing thestationarymember 24 first to be engaged by the heel-seat of the sole ofthe shoe and then to be received within the heel cup 42, carrying thesole along with it and turning the upper over the edges of the heel cup.Mechanism later to be described is provided for maintaining the turret44 in the position which it assumes at the completion of the heelturning operation, for the purpose of clamping the heel-seat of the shoeagainstthe been completed, the shoe S is held clamped,

the heel-seat lying in a substantially vertical plane, as shown in Figs.12 and 13, with the forepart of the shoe extending upwardly inconvenient position for the operation of the forepart turninginstrumentalities, which consist of a sole support 68, an upper orforepart spreader 70 and a turning iron 72, together with theirrespective supporting and actuating means which will presently be described. The upwardly extending sole of the shoe is bent about theforward end of the sole support 68 which'extends horizontally, andthe'forepart spreader 70 is then inserted into the forepart of the shoeto maintain the forepart distended and to hold the shoe in position foroperation thereupon by the turning iron 72 and the sole'support 68.Power actuated mechanism is then'started to causean advancing movementfirst of the turning iron 7 2 to bring it into engagement withthe toe ofthe shoe and then of both the turning iron 72and the sole support 68 toturn the forepart' of the shoe. In order to permit theforepart spreader70 to move in unison with the turning iron 7 2 and also to guide it inthe path of travel of the turning iron 72, the forepart spreader 70 iscarried by a rod 7 4 which slides'within a bearing 76 fulcrumed at 78 ona cover 121 secured to the head'20. The bearing 76 is normallymaintained tilted upwardly about its fulcrum 7 8 in order to swing theforepart spread or 70 out of the operators way during the turning of theheel portion of the shoe. The

forepart spreader 70 may be manually brought down by the operator forinsertion into'the forepart of the shoe for the purposes above stated,and mechanism presently to be described is provided for holding thebearing 76 down and thereby holding the 'forepart spreader 70 down inhorizontal or operative position. In order to facilitate manipulation ofthe forepart spreader 70, the latter is supported in a handle 80 of thepistol grip type which is adjustably attached upon the forward end ofthe rod 74. The shank portion of the forepart spreader 70 is providedwith a slot 82 (Figs. 8 and 9) through which extends a clamping pin 84,thereby permitting longitudinal adjustment of the forepart spreader 70.The shank of the forepart spreader 70 is curved in cross-section and isreceived against a concavely' curved face formed in the lower face ofthe pistol grip 80. As shown in Figs. 8 and 9, the slot 82 is relativelywide and the pin 84--is of relatively narrow diameter, therebypermitting a rotary movement of the curved shank with respect to thecurved bearing surface for adjustment of the forepa-rt spreader 70 aboutthe pistol grip v8O. Provision is also made for tilting adjustment ofthe forepart spreader 7O upwardly or downwardly by mounting the pistolgrip 80 upon a fulcrum 88 secured upon a sleeve 90 which is clamped uponthe end of the rod 74. An extension 92 of the pistol grip 80 is providedwith a slot 94 which receives an eccentric 96 journaled in a lug 98formed in the sleeve 90. Rotation of the eccentric 96 is effected bymeans of a handle 100 to swing the pistol grip 80 and the'forepartspreader 70 in a vertical plane. The fulcrum pin 88 forms a part of thepistol grip 80 and a portion 102 of the pin 88 is reduced diameter toaccommodate a setscrew 104 for securing it in adjusted position. Thereduced portion 102 is longer than the diameter of the set-screw 104 inorder to provide longitudinal adjustment of the pin 88,' therebypermitting translatory adjusting'movement of the forepart spreader. 70in a direction transverseto the direction of I movement of the turningiron 72. A setscrew 106 is employed to clamp the eccentric 92 inadjusted position. A pair of grooved wheels 108 are j ournaled in thefree end of the bearing '70 to permit the rod 74 to travel thereon witha minimum of friction. A single grooved wheel (not shown) is mounted onthe fulcrum pin 78 and carries the weight of the rod 74 at this point.For guiding the rod 74 a lever 110 is fulcrumed upon the head 20 and hasits free end connected by a link 112 to the rear end of the rod 74.

In order to cushion the rod 74 when it slides other end of the spring118 engaging the bearing for the pin 114 which is carried upon the mainarm of the lever 110. The spring 118 thus serves to take up the shockwhen the end of the pin 114 engages the abutment 116. Theabove-mentioned sole support 68 and turning iron 72 are carried upon aslide 120 which ism'ounted for reciprocation in ahorizontal planeinguideways 122 formed by the head 20 and the cover 121 (Fig. The solesupport 68 consists of an elongated member or bar and the toe turningiron 72 consists of a member appropriately formed both to bear againstthe toe of the shoe at the beginning of the turning operation andtoenter the toe ing iron 72 in its movement and also for holding itagainst upward movement with respect to the sole support 68. The solesupport 68, with the bar 124 upon it, is slidably carried upon a bar 128which is notched to receive the sole support 68. The bars 124 and 128and the sole support 68 are thus all carried by the slide 120 and areeach slidable with respect to the others and to the slide 120,"which isprovided with guide walls on each of its sides for preventing lateraldisplacementof the slidable members which it carries, and also with aflat cross-piece 129 for holding these members down. The turning bar 124and thebar 128 each have a lateral face provided with rack teeth130'a-nd 132 respectively. The bar 128 does not operate directly uponthe shoe and will hereinafter be termed a rack bar to distinguish itfrom the bar 124 of the turning. iron 72. Mounted for free rotation upona shaft 134 secured in the cover 121 Figs. 5 and 2). is anintegralmember comprising a pair of pinions 136 and 138, the pinion 136having a pitch diameter equal to twice the pitch diameter of the pinion138. The pinion 136 is constantly in mesh with the rack teeth 130 formedupon the bar 124 of the turning iron 72, while the pinion 138 isconstantlyin mesh with the rack teeth 132 formed upon the rack bar 128and, because the pinions136 and 138 constitute a unitary member androtate about a fixed axis, the travel of the turning iron 72 andof therack bar 128 will necessarily be interdependent and at the predeterminedratio of 2 to 1. The initial position of the sole support 68, that is,the position at which it is desired to maintain this support when thesole of the'shoe is bent over its operative or forward end preparatoryto inserting the forepart spreader 7 O in the upper of the shoe, isdeterminedby an adjusting screw 140 which is threaded in a bracket 142extending from the rear portion of the head in a position to enable thescrew 140 to abut the rearend of the sole support 68. A roll 159 Figs.12 and 13) supports the forward portion of the sole support 68. Theroll159 isjournaled in a bracket which, as shown in Fig. 1, is pivotallymounted upon the head 20 and extends forwardly therefrom. and carries :1depending abutment screw which rests upon the top of the fulcrum pin ofthe turret 26 for supporting this bracket in heightwise adjustableposition. After the forepart spreader .has been inserted in the shoe asabove described,the turning iron 72 is ad vanced into engagement withthe toe of the shoe. Thismovement of the turning iron 72 is effected bythe advance of the slide 120 by power-driven mechanism laterto bedescribed. Driving engagement between the slide 120 and the bar 124 ofthe turning iron 7 2 is effected throughan abutment 144 mounted upon thebar 124 and a lever 146fulcrumed upon a braclzet 148 which is carriedupon the slide 120. The lever 146eXtends downward ly from its fulcrumand is notched to accommodate the bars 124 and 128 and the sole support68, one edge ofthe notchbeingengageable with the abutment 144, As thelever 146 is freely pivoted upon the bracket 148, a spring 150 isinterposed between the bracket 148 and the lever146 to exert a yieldingdriving thrust upon the bar124, such thrust being sufficient to drivethe turning bar 124 against ordinary frictional resistance until theturning iron 72 encounters the toe end of the shoe on the forepartspreader 7 Mounted upon the lower end of the lever 146 and beneath therack bar128 is a transversely extending finger 152, which normally bearsagainst a shoulder on the slide 120 to maintain the lever 148 normallyin a vertical position against the force of the spring 150. Formed uponthe slide 120 and. extending rearwardly with an upward inclination is aguideway 154 for a clutch roll 156 which is normally urged downward. inthe guideway 154 by a weak compression spring 157. The backward yieldingof the lever 146, when the turning iron 7 2 encounters the resistance ofthe shoe, will cause the finger 152 to jam the clutch roll 156rearwardly and up the inclination of the guideway 154, causing the rollto exert an upward pressure on the rack bar 128 and, through the latter,upon the sole support 68. The upper surface of thesole support 68' willthus be clamped against the under face of the bracket 148. As shown in5, the upper surface of the solesupport 68 i slightly higher than theupper surface of the rack bar 128 to provide a reasonable clearancebetween the latter and the under surface of the bracket 148,'s0 that notmerely the rack bar, but both the rack bar and the sole support will beclamped to the slide 120. Sufficient clearance is provided in thebracket 148 for the free passage of the bar 124 even when the rack bar128 and the sole support 68 are thus clamped. The operation of theclutch roll 156 as above described serves to clamp togetherthe slide120, the sole support 68, and the rack bar 128, therei'hy causing boththe sole support 68, which has hitherto remained stationary, and therack bar 128 to advance in unison with the slide 120 and causing theturning iron 72 to be advanced at twice the speed of the rack bar 128,and therefore of the sole -support68 and the slide 120, through thepinions 136 of theslide 120 will carry the abutment 144i ahead of andaway from the lever 146, the roll 156 nevertheless will be held lockedby reason of the rearward thrust of the rack bar 128 upon it.

Upon the completion of its advance movement, the slide 120 is retractedto its initial position by the same power-driven mechanismwhichcaused itto advance. Ordinarily the roll 156 remains locked duringthe rearwardmovement of the slide 120, and the sole support 68 and the rack bar 128will be brought back withit, while the bar 124 of the turning iron 72will be returned at twice the speed of the :slide. The return :of theturning iron 7 2 will now restore the abutment 144 to its initialposition in engagement with the lever 146. a The abutment 144 engagesthe lever 146 slightly before the movement of the sole support 68 .isarrested by the stop screw 140, and the resistance of the spring 150,acting throughthe lever 146, the bar 124 ofthe turning iron, the gears186 and 138 andfinal'lyupon the rackfbar 128, will roll the clutch roll1556 forward relatively to the slide and thereby release its clampingaction; Even if, however, the release of the roll 156 were not to beeffected thus, the rearward 120 has formed thereon an abutment 153which, upon the return movement of the slide, engages the forward end ofthe rack bar 128 and thus retracts the rackbar; and the retraction ofthe rack bar, through the gears 136 and 168, drives the turning iron 7 2backward; The sole support 68 ordinarily will be returned byitsfrictional contact with the bars 124 and'128, but should it encounterany accidental resistance, it will be returned positively by the rearend of the rack bar 128 engaging apin 155 which depends from the undersurface of the sole support 68 at a point adjacent to the rear endthereof. The sole support 68will thus be returned to substantially'itsinitial position, provision being made for reasonable clearance toprevent the rear end ofthe sole support 68 from being driven positivelyagainst the stop-screw 140.

The slide 1 20 is driven through a link 158 (Fig. 2) from the freeend ofa lever 160, the opposite end of which lever is journaled upon a shaft162 secured by a set-screw 164 in the head of the machine. Formed in thelever 160 is a guideway 166 for a cross-head 168, the cross-head 168being driven by a crank 170 upon a main driving shaft 172 which is journaled in the head 20. This construction provides for a relativelyslow advancing movement of the slide 120 during the turning operationand a relatively quick return at the completion of the turningoperation. Motive 5 drives a pulley 182 which is freely rotatable upon adrive shaft 184 journaled ina bracket 186 secured to the standard 22.The web 188 of the pulley 182 is formed toconstitute one member of adisk clutch the other member 190 of which is keyed upon the shaft 184for longitudinal movement thereupon. A spring 192, surrounding the shaft184 and interposed between a bearing'on the bracket 186 and the hub ofthe clutch member 190, tends to urge the member 190 into clutchingposition. Control of the rotation of the shaft 184 is effected by aforked lever 194 which straddles the hub of the clutch member 190 andwhich has a pair of inwardly extending fingers which wereceived in aperipheral groove in the hub so that upon counterclockwise movement ofthe lever 190 as viewed in Fig. 2, the clutch member 190 is pulled awayfrom the clutch member 188 against the force of the spring 192. Thelever 194 is fulcrumed upon an eccentric 196 which is j ournaled in' thebracket 186.

Adjustment of the fulcrum 196 longitudinally of the shaft 184 may beeffected by rotation of the eccentric 196 which-has a slotted end toenable it to be turned by a'screwdriver. A set-screw 198 is providedformaintaining the eccentric 196 in adjusted position. The freeend of thelever 194 is controlled by instrumentalities which will later bedescribed. It is desirable that immediately upon the unclutching of themembers 188 and 190 the'rotat-ion of the shaft 184 be stopped. This isaccomplished by means of a brake 200 which is threadedly adjustable inthe bracket 186 toward or from the outer face, of the clutch disk 190and which is engaged by the outer face of the clutch disk 190 upon themovement of the latter to unclutching position. Keyed upon the shaft 184is a worm 202 which meshes with a worm Wheel204' freely rotatable uponthe main drive shaft 172. Fixed Within the worm wheel 204 are aplurality of clutch plates 206 which alternately engage a plurality of.similar clutch plates 208 secured upon a clutch member 210 Which iskeyed upon the shaft 172. Driving pressure between the plates 206 and208 is maintained by means of a spring 212 which surrounds the shaft 172and is interposed between the hub of a clutch cover member rate-baa213,fwhich is keyed upon the shaft-172, and the hub of an adjustingwheel 214 threaded upon the end of the shaft'l72. Through the adjustmentofthe pressure of the spring 212, h

the clutch plates 206 and 208 may be permitted to slip when theoperatinginstrumentalities of the machine encounter an unusualresistance, predetermined in amount, to prevent damage to the shoe.

Mechanism is provided for automatically; I

bringing the machine to rest after the completion of the turningoperation. This mechanism is. controlled by a cam 216 in the form of aneccentric'which is rotatable with the sha'ft172,beii1g, as shown in'Fig;3,

ally connected to the free end of the clutch control lever 194, the cam216 being so positioned with respect to the rocker arm 220 that when theshoe turning instrumentalities are at the beginning or the completion oftheir operative movements, the rocker'arm 224 will hold the link 228against the thrust of the spring 192 and willthereby hold the clutchmember 190 out of clutching engagement spring 192 to urge the clutchmember 190 in to engagement with the clutch member 188. Such liftingofthe link 228 is effected by a tripping pawl 232pivotally mounted upon acontrol handle or lever 234 which is fulcrumed at 236 upon the bracket186, the pawl 232 having a slight relative pivotal movement with respectto the lever 232, being urged forwardly therefrom by a compressionspring 238. A tension'spring240interposed between the-bracket 186 andthe lever 234 urges the lever'234 normally in a counterclockwisedirection as viewed in Figs. 1 and 2, tending'normally to maintain thepawl 232 below the level of the shoulder 226. -The normal position ofthelever1234 under the in fluence 'of the spring 240 is determined by astop 237 (Fig. 1). Assuming now that the machine is at rest, it may bestarted by a clockwise movement of the lever 234 as viewed in Fig. 2, astop 235-being provided to limit the movement of the lever 234 in thisdirection. The effect of such movement is to raise the pawl 232, therebylifting the end of the link 228 and raisingthe plate 226 clear of thefree or latching-end of the rocker arm 224, and thereby effectingengagement of the clutch members 188, 190 and, through such engagement,effecting rotation of the shaft 184, thus causing, through'previouslydescribed mechanism, rotation of the main drive shaft 1-72. As the maindrive shaft 172 rotates, such rotation taking place in a clockwisedirection as indicated by the arrow shown in Figv2, the cam 216 willpermit a counterclockwise movement of the rocker arm 224 until-the freeend of the latter travels toward the left beyond the edge ofthe plate226. Continued rotation of the shaft 172 will cause the cam 216 to movethe rocker arm 220 and thereby the rocker arm 224 in a clockwisedirection, and such movement will cause the free end of the rocker'arm224 toengage the edge of the plate 216 and pull the link 228 bodilytoward the right,

. thereby moving the clutch member 194 away from the clutch member 188andinto engagement with the brake 200, stopping the operation of themachine definitely at the end of a cycle. The lever 234, meanwhile, andimmediately upon release of the grasp of the operator,has been restoredby the-spring 214 to its normal position, and the above-describedmovement of the link 228 toward the right will cause the plate 226 topass above the pawl 232 and thereby restore the mechanism to readinessfor a further operation. Even if, however,the operator shouldinadvertently retain his grasp upon the control lever 234, theabove-described mechanism will not initiate a second cycle ofoperation,because the above-described movement of the link 228 will mcreiy serveto push the'pivotally mounted pawl 232, now in raised position, to theright against the-force of the spring 288. Release of the control lever234 will then lower the pawl 232, permitting it to pass under the plate226 to its normal position of readiness to initiate another cycle.

if unusual circumstances should render manipulation or adjustment of theshoenec essary, or if some other emergency should arise, the operatorcan stop the machine at any point in its cycle by depressing a treadl-e241 Fig. 1) thereby exertingan upward thrust through a rod 239 which ispivotally connected to one arm of a bell-crank 243 2) which is freelyrotatable-upon the shaft 222. The bell-crank 243. is thereby rotated ina clockwise direction. as viewed in F ig. 2, and its other arm willengage the plate 226,

which-extendstransversely of the link 228 e it to he thus engaged. Ifnow, the

lint 228 should be in anyposition other than ter-pin 256.

that at which it holds the clutch member 190 against the brake 200 andaway from the clutch member 188, the depression of the treadle 241 willmove the link 228 to such position. Upon release of the treadle 241, thelink 228 will bercstored to the control of the cam 216, and theoperation of the machine will be resumed at whatever point in the cycleit was stopped.

As above stated, mechanism is provided for holding the forepart spreader7-0 down during the advance of the turning irons 68 and T2. Suchmechanism controlled by a cam 2 and 3) in th form of acylindricalsegment which is concentric with the azris of the shaft 172and which is mounted upon a cam disk 244 carried upon the shaft 172. Aroll 246, adapted to ride upon the outer surface of the can1242, iscarriedupon one arm of a belhcrank 248 fuicrumed upon the shaft 162,the-other arm of the bell crank 248 being pivotally connected to a link2550 (Figs. 1 and which has its upper end pivoted to the bearing 76.When the forepart spreader 70 in raised or inoperative position, theroll cam 242. When the operator'lowersthe forepart spreader, the roll246 IS moved, through '90 4 6 assumes a position within the segmentalthe bell crank'248, outwardly to a position wherein the periphery of theroll 246 is at substantially the-same radial distance from the axis ofthe earn 242 as the outer periphery of the cam itself is. The segmentalcam 242 has its opening so positioned thatv when the machine is at rest,the roll 246 may pass therethrough. The operation of the machine thenhaving been initiated, the rotation of the shaft 17 2 will bring the cam242 into a position wherein the roll will ride upon the periphery of thecam 242thereby preventing return of the bellecrank 248 to its formerposition and will thus hold the'members which carry the forepartspreader 70 in operative position; i As the cycle of operation of themamerit, thereby permitting the forepart spreader TO to be raised by theforce of a torsion spring 252 which surrounds the hub of the bell-crank248. One end of the spring 252 acts against a flanged portion of thebellcrank 248,tending-to rotate thebell-crank 248 into position to raisethe bearing 76,. the opposite end of the spring 252 being anchored in acastellated nut 254 which is threaded upon the'end of the shaft 162 andwhich is held in adjusted position thereupon by a cot- As shown in Fig.12, the forepart'spreader 7 O has a slight downward inclination towardits toe end, and the sole of'the shoe S is interposed between theforepart spreader 70 and the sole support 68. The most satisfactoryco-operation between the turning iron 72 and the forepart spreader 70 isobtained when the toe end of the latter is spaced no further from theupper surface of the sole support 68 than is required by the thicknessof the sole of the shoe S. In order to maintain. the forepart spreader 7O in such a position without resorting to delicate heightwise adjustmentfor soles of varying thickness, and also to accommodate inequalities ofthickness in various portions of a sole, the above-mentioned pivotalconnection between the link 250 and the bell-crank 248 includes a sleeve251 (Fig. 2) through which-the link 250 freely slides. The sleeve 251 isthreaded through a block 253 which is pivotally connected to thebell-crank 248. Surrounding the link 250, and interposed between thesleeve 251 and a nut threaded on the lower end of the link 250 is acompression spring 255 which serves yieldingly to maintain the toe endof the forepart spreader down upon the sole of the shoe 5. hen, now, thelink 250 is moved upwardly by thespring 252, and is stopped by the roll246 engaging the inner surface of thecam 242, the inertia of v theupwardly moving parts will be absorbed by the spring 255.

V The above-mentioned means for locking the heel cup turret 44 inoperative position is controlled by the rotation of the main shaft 172through the instrumentality of a roller 258 (Fig. 2) and a half roundpin 260 mounted adjacent to each other upon the face of the cam disk 244which is opposite the cam 242. The pin 260 is held in adjusted positionby a set screw 261. The flat surface of the half round pin 260 isengageable with a concavely formed end portion of a lever 262 which issecured on a shaft 264 fixed in the head 20. Angular adjustment of thelever 262 about the shaft 264 is provided by a pair of set screws 266threaded through the hub of the lever. 262 and having their endsabutting squared-off surfaces formed upon either side of the shaft 264.Mounted upon the shaft 264 and held against rotation with respectthereto by a key 268 (Fig.7)

is a hub 270 of a clutch actuating member 274 being freely slid'ablethereover. Above both the rod 278 and the locking bar 274 is an abutment280 having an inclined lower face and between this inclinedl'owerface'and the upper face of the bar 274 is interposed a clutch roll 282.V Extending outwardly from theoface of the depending flange 272 is apair of fingers 284' for engaging the roll 282 upon '5 each side thereofto move it into or out of a .s rin 302.

'No yielding movement of, the locking bar '27 4 is necessary to developthe full clutching effect of the rod 282, and lost-motion tending toloosen the clamping grip of the members 24 and 42 upon. the heel seat oftheshoe is thus eliminated. Secured upon the ends of the fingers 284 isa retaining plate 286, the roll 282 being held against movementin adirection transverse to the bar 274 by the retaining plate 286 and thedepending flange 272., In order to providefor up or downadjustmentof'the abutment 280 so that the roll 282, when in clutchingposition, will be substantially over the rod-27 8, the abutment 280 isnot mounted directly upon the head 20 but is journaled upon an.eccentric peripheral portion 288 of-a sleeve 290 which is mounted forrotation in the head 20, the sleeve 290 constituting a bearing in whichis journaled the shaft 264. Formed on theend ofthe sleeve 290 is aflange 292 having formed therein a pair of arcuate slots 294.

(Fig. 1). which are concentric with the axis of the shaft 264 and whichmay be clamped by a pair of clamping bolts 296 in any desired positionof adjustment. Rotation of the sleeve 290 will, through its eccentricportion 288, serve toraise or lower the abutment 280 as may be desired,rotation of the abutment being prevented by a pin 298 which engages avertical slot 300 formed in the abutment 280. A spring. 302 tends tourge the'lever 262 upwardly and to throw the clutch roll 282 intoclutching position to lock the bar 274 and thereby the heel cup turret44. Assuming the turning of the heel portion of the shoe to have beencompleted, the operator, while still holding his foot upon the treadle54, initiates the operation of the forepart turning instr'umenta'litiesthrough the control lever 234 in the manner previously described; At thebeginning of the rotary movement of the shaft 172, the flat surface ofthe half round pin'260 is in engagement with the concavely formedportion ofithe free end tion of the shaft 172, however, the half roundpin- 260 is carried beyond the end of the lever 262, allowing the laterto be snapped by the spring 302 into locking position and thereafterrendering itrunnecessary for the operator to retain his foot on thetreadle 54.

After the forepart turning instrumentalities have completed theiroperation upon the shoe and as they are being restored to their initialpositions, the roller258 engages and rides under the concavely formedportion of the end of the lever 262, therebyunlockingthe After arelatively slight r0taclutch roll 282 and releasing the heel cup turret44, which is now free to return under the influence of the spring 56 toits inoperative position. The purpose of the half round pin 260 is toprovide a more sudden release of the lever 262 than could beaccomplished by relying upon the roller 258, since the latter, by reasonof its appreciable diameter, wouldnecessarily effect a slower releasefor the lever 262 than the hal round pin 260.

The advantage of the quick release for the lever 262 is that it insuresimmediate and reliable clutching engagement of the roll 282. In order toenable the operator to release the heel cup turret 44 at any point ofthe cycle of operation of the machine, the lever 262is extended beyondthe shaft 264, the righthandend of the lever 262, as viewed in-Fig. 2,being shaped to provide a convenient hand grip 306. By pulling up thehand grip 306 against: the force of the spring 302 the roll 282 may bereleased at any timeand the turret 44 unlocked. '1

A stationary hook-shaped member 304 is provided for use in smoothing outmanually any wrinkles that may remain in the toe portion of a shoe afterthe shoe has been turned by the above described instrumentalities.

In the operation of themachine, the heel portion of the shoe S is placedover a selectively positioned heel cup 42 with the upper of the shoe Sextending outside of the cup 42. Depression of the treadle 54 thereuponserves to swing the turret 44 and the heel cup with the shoe S upon ittoward a selectively positioned stationary member 24, causing the latterfirst to be engaged by the heel seat of the sole of the shoe and then tobe received within the heel cup 42, the heel seat thus being forced intothe cup and the upper of the shoe being turned over the edges of thecup. The operator, with his foot still on the treadle 54 to maintain aclamping pressure upon the heel seat of theshoe S between the stationarymember 24 and the base of the heel cup 42, then bends the sole ofthe-shoe S'over the end of the sole support 68 and inserts the forepartspreader 70 into the forepart of the shoe. Still keeping the heel seatof the shoe clamped, he starts rotation of the shaft 170 by a movementof the handle 234. As soon asthe shaft 170 has rotated through a. smallfraction of a revolution, the segmental cam 242 will operate to maintainthe torepart spreader 70 down without further attention on the part ofthe operator, and the pin 260 will be carried beyond the end of thelever 262, allowing the latter under the influence of the sprin 302 tolook the heel cup 42 in heel-seat clamping position and therebypermitting the operator to withdraw his foot from the treadle 54.Continued rotation of the shaft 172 advances the slide 120, causing theturning iron 72 to engage the toe end of the shoe S. The resistancewhich the turning'iron 7 2 encounters uponengagement with the toe end oftheshoe causes both the sole support 68 and th'ebar 128 to be .clampedsimultaneously to the slide 120. and, thus to be advanced in unison withthe slide 120, while the bar 128, operating through the gears 138 and136, driv'es'the, turning iron .7 2 i at twice the speed of the solesupport 68. As the turn ng iron 7 advances, the forepart spreader 70recedes, and the shoe S is proinitial positions and also to releasethefore-.- I

part spreaderYO to permit it to swing upwardly out ofthe way. During theretrac tion of the slide 120 the rotation of the shaft 17 2 serves.alsotounlockthe turret 44 .and to release'the' heel seat of the shoe Sfrom, the

clamping grip of the heel'cup 42against the stationary'member 24.
